Title: Dryer belt and method of making same
IPC: D21F1/00
Filed: 1964-05-21
Abstract: 1,016,649. Seaming non-metallic sheet material; punching apparatus. HUYCK CORPORATION. May 21, 1964 [May 24, 1963], No. 21127/64. Headings B4B, B5K and B5N. [Also in Division F4] In a method of producing a belt for the drying section of a paper-making or similar machine, a sheet of substantially incompressible fdlymeric material such as polyethylene terephthalate is perforated to provide a series of spaced perforations substantially entirely throughout, preferably with uninterrupted paths extending longitudinally of the belt, and joining the end portions of the sheet to form a belt movable in an endless path. A layer of compressible material, e.g. open-cell foam or a bat of fibrous material, may be laminated to the belt. Punching apparatus.-The perforations are formed, after sheets of the material have been sealed in side-by-side relationship, by a punching apparatus, Fig. 3 (not shown), comprising a series of cylindrical, downwardly-extending punches which are movable in directions perpendicular to the plane of the sheet or sheets. The lower surfaces of the punches are recessed to form sharp cutting edges and are at a temperature below the softening point of the material. The perforations are from 0À01 to 0À25 inch in diameter and the number of perforations from 10 to 6000 per square inch. Seaming.-The ends of the webs are joined by ultra-sonic welding apparatus 70, Fig. 7, including a sine wave voltage source 71 connected to a transducer 72 arranged to impart vibratory mechanical motion at a fixed ultrasonic frequency to a welding element or horn 72a. The ends of the belt 60 may be formed with a 45 degree bevel 78 and may be moved along a table 75 beneath the horn, or the belt may remain stationary and the welding apparatus may be moved relative thereto. In another embodiment the sheet is adhesively interconnected or is joined by lamination, e.g. by a polyester tape. In the embodiment of Figs. 8 and 9 (not shown), the ends of the belts are folded back upon themselves, held in place by stitching and the folds are notched to provide integrally formed loops which are interleaved and an elongated rod is inserted through the loops to form the endless belt construction. In the embodiment of Figs. 10 and 11 (not shown), the end portions of the web have transversely extending webs stitched thereto with clipper hooks sewn thereto to replace the loops of the prior embodiment. Laminating.-A drier belt is formed of a non-woven batt of natural or synthetic fibres which may be pre-formed, e.g. by needling, felting, chemical bonding which batt is laminated to a sheet of polyester film. The fibres forming the batt may be given a predetermined orientation by electrostatic deposition on the sheet, and the batt is secured as by a polyurethane resin adhesive to the sheet. In Fig. 5 (not shown), a layer of open cell plastic foam e.g. polyurethane resin, is laminated to a sheet of perforated polyester film by a suitable adhesive.

Title: Automatic radioactive sample changer
IPC: G01T7/08
Filed: 1962-07-01
Abstract: 974,253. Handling radio-active material. ATOMIC ENERGY OF CANADA Ltd. June 1, 1962 [July 21, 1961], No. 21272/62. Heading B4Q. An automatic sample changer for moving radio-active samples 15 between a storage station 10 having upper and lower shielded chambers 13, 14 and a counting station 11 including a lead castle 16 containing counters 17, 18, comprises a slide 20 having an aperture for receiving a sample, the slide being reciprocated in a track 22 by a linkage 30, 32 driven by a member 34 carried by a rotatable member 28. One revolution of the member 28 in either direction causes the slide aperture to be moved from a storage position in alignment with the chambers 13, 14 to a counting position within the castle 16 and to return to the first-mentioned position. A reversible motor 26 drives the member 28 through gearing 27 and a one-way clutch including a spring-biased pawl (Fig. 8, not shown) so that the slide 20 is normally reciprocated only when the motor is driving in the forward direction; the clutch may, however, be overridden so that the slide is reciprocated for both forward and reverse driving of the motor. The samples 15, which are stacked within the chambers 13, 14, are transferred singly into the slide aperture by a plunger 36 attached to a lead screw 37 axially moved by a nut 38 driven by a chain 40. The chain is driven by the motor 26 through a gear 42 coaxial with the member 28, the arrangement being such that operation of the motor sufficient to rotate the member 28 through one revolution causes the plunger 36 to be moved a distance equal to the thickness of one sample 15. When the motor 26 is driving in the forward direction the plunger 36 moves downwards whereas when the motor is reversed the plunger moves upwards. In operation all the samples are initially stacked in the chamber 13 and the motor 26 is operated in the forward direction, whereby the slide 20 transfers a sample into the castle 16, a time switch 45 operated by a cam 44 on the link 32 causing the motor circuit to be interrupted for a predetermined period of time to enable the counting to take place. When the sample arrives back at the station 10 it drops into the chamber 14 on to the plunger 36 and the next sample is received in the slide aperture. When the last sample leaves the chamber 13, a switch (Fig. 5, not shown) is operated and the cycle continues as before until a switch 46A is closed by the link 32, whereupon the motor 26 is reversed. The clutch driving the member 28 now slips so that the plunger 36 lifts the stack of samples back into the chamber 13. However, if the clutch is overridden the slide 20 is also operated and the samples are returned to the chamber 13 after a second counting in the castle 16. When the last sample leaves the chamber 14, a switch (Fig. 6, not shown) is operated and the motor is again reversed.

Abstract: 426,088. Rotary abrasive tools. BRITISH UNITED SHOE MACHINERY CO., Ltd., RICKS, F., HOPE, E., and BARCLAY, W. R., Union Works, Belgrave Road, Leicester. July 29, 1933, Nos. 21334/33, 3840/34, and 16680/34. [Class 60] A Naumkeag tool, for abrading in sharp corners in the manufacture of shoes, comprises a body portion carrying an annular cover member moulded from a band of abrasive sheet material, the apical angle of which, that is the angle between straight lines extending in a plane containing the tool axis from a point on the extreme outer periphery to the edges of the cover member, is not greater than 90‹. The tool may comprise a metal disc 5 covered with a felt body 3 to which the abrasive cover 12 is attached by a clip at its ends or by an adhesive, such as that used on adhesive tape, which allows the used cover to be stripped off and replaced by a new one. To avoid lifting of the overlapped end of the cover by contact of the edge with the work, the inner face may be skived off, or a short bevel 13 may be provided on the body 3 so that the two ends are supported at different levels. Alternatively, the tool may comprise a peripheral inflatable ring 15 having on its inner side a tongue 17 which is gripped between the flanged edges of the body 3 of the tool and a cover member 7, which are drawn together by a nut 13. The cover 27 is placed over the ring 15, which is then inflated to grip the cover by air supplied through the hollow shaft 1 and a pipe 21. The portion of the ring at which the lapped joint of the cover is situated may have a recess moulded in it, of slightly greater length than the joint, and of a depth equal to or slightly greater than the thickness of the abrasive sheet. Flint particles may be moulded in the surface of the ring to cause it to grip the cover effectively. The covers are conveniently made from strips of abrasive-covered woven sheet material cut on the bias, the strips being softened by moistening and then stretched round a helically-formed threadlike projection 43 on a wooden cylinder 41. The material curls itself round and conforms to the section of the helical projection, and maintains this form after being allowed to dry on the mould.

Abstract: 1,145,831. Aminoplast coating compositions. BRITISH INDUSTRIAL PLASTICS Ltd. 16 May, 1966 [20 May, 1965], No. 21388/65. Headings C3B and C3R. [Also in Division C7] Alkylated aminoresins, derived from the alkyl esters of aminoplast precondensates, or the precondensates themselves are at least partially transesterified by reaction with a hydroxycarboxylic acid. The resins or precondensates may be obtained by reaction of HCHO with urea, melamine or benzoguanamine; they may be alkylated by reaction with methyl, ethyl, propyl or butyl alcohol. The hydroxycarboxylic acid may contain more hydroxyl than carboxylic groups, e.g. gallic acid or dimethylolpropionic acid. Other suitable acids are glycollic acid, lactic acid or acids obtained by condensing a glycol with a dicarboxylic acid or anhydride. The hydroxycarboxylic acid and resin or precondensate may be reacted together in the absence of solvent (optionally in vacuo) until the evolution of alcohol ceases; sufficient acid may be used to provide one OH group for each mole of alkylated resin or precondensate. The resins of the invention may be used to form ionized aqueous solutions (e.g. having a pH from 6À5 to 9À0) in which the anion is derived from the resin and the cation is provided by ammonia or an organic base (e.g. triethylamine or dimethylaminoethanol). Such solutions may be used together with water soluble alkyd resins and pigments in the formation of enamels which may be coated by electrodeposition (see Division C7).

Title: Improvements in or relating to systems for heating water or other liquids
IPC: F24H1/18
Filed: 1945-08-24
Abstract: 606,969. Heating water &c. AKTIEBOLAGET ELEKTROLUX. Aug. 24, 1945. No. 21708. Convention date, Oct. 26, 1944. [Classes 64(i) and 64(ii)] In heating water or other liquid in a tank by a heat transfer system with a heat-rejecting member, e.g. a condenser, in heat exchange relation with the liquid, a single uppermost stratum of liquid in the tank is heated until it reaches or approaches a predetermined temperature, the next lower stratum is automatically heated next, and so on downwardly. In the form shown, water in the tank 1 is heated by means of a closed circulating evaporating-condensing system which contains distilled water and nitrogen. Initially, when the system is cold, the water occupies part of the boiler 2, and the nitrogen fills the remainder of the system, including the coil 8 and the air-cooled condenser and gas reservoir, which may be either a single vessel 10, as shown, or separate vessels with the condenser leading to the gas reservoir. When the boiler 2 is heated, the steam produced displaces the nitrogen first from the top of the boiler and then from the tube 7 until it reaches the upper part of the coil 8. Here the steam condenses and heats the adjacent water at the top of the tank 1. The rest of the coil contains only inert gas and condensate returning to the boiler 2, so that the water in the tank below the topmost layer is heated very little. The steam continues to heat the water in the topmost layer until the temperature of that layer of water reaches that of the steam. The latter then flows further down the coil until it is completely condensed, and further compresses the inert gas in front of it. This process continues until all the water in the tank is heated to the required temperature, when the coil is filled with steam and all the gas is compressed in the vessel 10, in which the steam from the coil 8 is condensed. A thermostat 4 then shuts' off the burner 3 or other heating means. The gas reservoir may be located at 108 within the tank 1. In a modification, instead of the inert gas and a condenser-reservoir 10, a column of water is used to provide the necessary pressure in the closed circulating system.
